llhis invention relates to a threshing and mowing machine.

An object of the invention is the provision of a device in the shape of a seed pan and an oscillating perforated plate movable over the pan and connected to a moving part of the threshing machine for causing oscillation of the plate, said plate being stepped in order to provide for the discharge of the straw or hay from the plate.

Another object of the invention is the provision of an attachment for a threshing machine in which a perforated plate is slidably mounted upon a seed pan and which plate reeeives the hay or straw which is agitated by the perforated plate for releasing the seeds from the straw and permitting said seeds to 7 drop through the perforations in the plate, said pan having slots to receive guide bars noun-ted on the inner face of the perforated plate so that when the plate is reciprocated by a moving part of the threshing machine said plate will have a composite movement longitudinally and transversely of the said pan.

A further object of the invention is the provision of an attachment for a threshing machine and including a perforated stepped plate adapted to be oscillated on a seed pan for 7 causing the release of the seeds from the straw whereby said seeds will pass through the perforations and will be collected in a seed pan below the oscillatable plate, the plate being so constructed that it will cause the straw to be moved away from the usual cutter bar.

This invention will be best understood from a consideration of the following detailed description, in view of the accompanying drawings forming a part of the specificastructed in accordance with the principles of my invention,

Referring more particularly to the drawings, 1O designates a cutter bar having folded straps l1 and 12 secured to the bar,said straps. at their inner ends being formed into a loop shown at 13 to provide an elongated bearing 14 for a rod 15. This rod extends longitudinally within a seed pan 16 and adjacent the edge which is associated with the cutter bar 10. r I v I The seed pan has its inner end 17 closely associated with the cutter bar 10 and its outer end 18 of a considerably greater height than the-inner end so that the'oscillatable plate 19 will be tilted at an angle to the horizontal when said plate rests upon the open upper end of theseed pan. Straps 20 are secured to the outer end wall 18 and disposed in engagement with the bottom of the pan. 'The.

inner ends of the straps are bent around an outer surface of the cutter bar 10 secured thereto by means of bolts 21. V

The seed plate 19 has a stepped formation and is provided with a plurality of perforations 25 through which the seeds are adapted to pass and to be collected in the pan 16. The outer edge of the plate 19 has a downturned lip 27 adapted to engage over the re inforcing bar 28 secured to the upper edge of];

the end wall 18 of the seed pan. The inner edge of theplate .19 lSfOIlHQCl into a sleeve to receive the bar 15 and straps 29 extend widthwise of the plate 19 andare secured thereto in any appr ved manner. The inner ends of the straps are formed into collars as shown at 30 and receive the rod 15.

A bar 32 is secured to the under face of the stepped plate 19 and has an angularly disposed portion 33 received within a slot 34 of a side wall 35 of the seed pan 16. The other end of the bar 32 is bent upwardly as shown at 36 to engage over the upper edge of a side wall 37 of the pan and is then bent downwardly and upwardly to form an angular i seed a A bell'crank lever 45 is pivotally mountedn at 46 on a flange 47 projecting from the inner portion 38 with thefree end of the angular portion secured to a depending flange 39 of i r the plate 19. Theopposite end of the bar 32 is'shown'at 40 and has an angular portion which extends downwardly so that when the plate 19 is reciprocated the angulari portion 40 of thezbar will cause the 'pl'ateT19 to rise along that edge while the angular portion 38 will cause thefopposite side edge of theplate to be elevated above; th;e 'upperedge of-the pan 16.

1 1 U-shaped member 53 has itsbridging portion pivotally connected'at54 to the short arm of the'bell crank lever.- The legs of the U-shaped member are provided with alined passages to receive one'end of the rod 15 and said rod is' secured to the legs softhatwhen i the plate 19 over the bellcrank lever is rocked the U-shaped member] will be moved in a lineal manner while the'rod'15 will be reciprocated.

This distance is limited'by the length of the short arm of the bell crank leverand i also by the length of the bearing surfaces 14 ofthe bentstraps 13. The fact that the bars or straps 29are not Y only secured to the'inner face of the plate 19 but are also secured to the rod 15 provides for a reinforcement of the top 'so' that the movement is transmitted to the rod 29 rather H than directly to the plate 19.

As has been previously stated, the reciprocating movement of the -plate :19causes the
